About this data
How to read this page
Star ratings vs. Care Quality Score: The Google star rating reflects visitor and family opinions collected from public reviews. The Care Quality Score is an independent metric derived entirely from federal inspection data — the two measure different things, and comparing them side-by-side gives a fuller picture.
Where this data comes from
All clinical data on this page originates from the Centers for Medicare & Medicaid Services (CMS), the federal agency that certifies and inspects every Medicare- and Medicaid-participating nursing home in the United States. Reviews are imported verbatim from public Google business listings.
What to do next
Data is a starting point, not a final answer. We encourage families to visit facilities in person, observe daily routines, and speak with staff and residents. See our guide: Questions to Ask When Visiting →
